Catheter securement device with window

ABSTRACT

An anchor system for securing a catheter to a patient may include an anchor pad, which may include a lower surface, an upper surface, and a window extending through the anchor pad. The lower surface may include an adhesive layer to adhere the anchor pad to skin of the patient. The upper surface may include a catheter securement mechanism. The window may provide access to the skin of the patient for application of a topical skin adhesive at a catheter insertion site disposed within the window.

BACKGROUND OF THE INVENTION

A clinician may insert a vascular access device into a blood vessel of a patient to infuse fluid and/or draw blood. The vascular access device may first penetrate skin of the patient at an insertion site, and when the vascular access device is properly placed within the blood vessel, the clinician may apply a skin adhesive at the insertion site to secure the vascular access device. In order to apply the skin adhesive at the insertion site, the clinician may hold the inserted catheter in one hand and use another hand to open an adhesive container and apply the skin adhesive. After applying the skin adhesive to the insertion site, the clinician may hold the vascular access device while the skin adhesive dries. Securing the vascular access device via the skin adhesive may thus be a difficult and messy process that may result in dislodgement of the vascular access device, ineffective application of the skin adhesive through application of too much or too little of the skin adhesive, or adhering of the skin adhesive to a hand or glove of the clinician. Accordingly, there is a need in the art for devices, systems, and methods that provide securement of the vascular access device in a controlled, safe manner.

BRIEF SUMMARY OF THE INVENTION

The present disclosure relates generally to devices, systems, and associated methods to secure and stabilize a vascular access device inserted into a blood vessel of a patient. In some embodiments, an anchor system to secure the vascular access device to the patient may include an anchor pad, which may include a lower surface, an upper surface, and a window extending through the anchor pad. In some embodiments, the lower surface may include an adhesive layer to adhere the anchor pad to skin of the patient. In some embodiments, the window may provide access to the skin of the patient for application of a topical skin adhesive at an insertion site of the vascular access device, the insertion site being disposed within the window.

In some embodiments, the skin adhesive may be disposed within the window to secure the vascular access device in place at the insertion site. In some embodiments, the window may enclose the insertion site, which may facilitate controlled and contained application of the skin adhesive at the insertion site. In further detail, the skin adhesive may contact the skin of the patient within the window, but may be prevented or discouraged from contacting skin of the patient outside of the window, reducing a likelihood of a messy application of the skin adhesive. In some embodiments, the skin adhesive may provide localized stabilization of the vascular access device at the insertion site and/or may provide a seal around the vascular access device at the insertion site, which may prevent infection. The skin adhesive may also increase an indwell time for the vascular access device.

In some embodiments, a securement mechanism may be disposed on the upper surface of the anchor pad and may secure the vascular access device to the anchor pad. In some embodiments, the securement mechanism may include an adhesive well. In some embodiments, the securement mechanism may include a retainer capable of receiving a portion of the vascular access device. In some embodiments, the retainer may be coupled to the upper surface.

In some embodiments, the anchor pad may include a release liner that may cover the adhesive layer and may be removed prior to adhering the anchor pad to the skin of the patient. In some embodiments, the anchor pad may include a slot that may extend from the window to an exterior of the anchor pad. The slot may allow the vascular access device to be inserted into the patient prior to positioning and securing the anchor pad to the skin of the patient.

In some embodiments, a method of securing the vascular access device may include providing the anchor pad and/or the securement mechanism. In some embodiments, the method may include inserting the vascular access device into the patient at the insertion site. In some embodiments, the method may include adhering the anchor pad to the skin of the patient via the adhesive layer. In some embodiments, the method may include securing a portion of the vascular access device within the securement mechanism. In some embodiments, the method may include applying the skin adhesive at the insertion site and/or proximate the insertion site within the window after the vascular access device is inserted at the insertion site and after the anchor pad is adhered to the skin of the patient.

In some embodiments in which the anchor pad includes the slot, adhering the anchor pad to the skin of the patient via the adhesive layer may include placing the window around a vascular access device via the slot, the vascular access device having been previously inserted at the insertion site. In some embodiments, adhering the anchor pad to the skin of the patient via the adhesive layer may include removing the release liner covering the adhesive layer.

DETAILED DESCRIPTION OF THE INVENTION

The presently preferred embodiments of the described invention will be best understood by reference to the Figures, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures in the present disclosure, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments, represented in FIGS. 1 through 4, is not intended to limit the scope of the invention, as claimed, but is merely representative of some embodiments of the invention.

Referring to FIGS. 1A-1B, an example anchor system 10 for securing a catheter 12 to a patient is illustrated. It is understood, however, that the anchor system 10 may be utilized in connection with other vascular access devices, including, but not limited to, fluid supply and drainage lines, feeding tubes, chest tubes, scopes, connectors, adaptors, electrical wires and cables, and the like, any of which may be secured to the patient by the anchor system 10.

In some embodiments, the anchor system 10 may include an anchor pad 14, which may include various shapes and sizes. In some embodiments, the anchor pad 14 may include a lower surface 16, an upper surface 18, and a window 20 extending through the anchor pad 14. In some embodiments, the lower surface 16 may include an adhesive layer 22 to adhere the anchor pad 14 to skin 24 of the patient.

In some embodiments, the upper surface 18 may include a catheter securement mechanism, such as, for example, a retainer or another suitable mechanism. In some embodiments, the retainer 26 may be coupled to the upper surface 18 and may be capable of receiving a portion of the catheter 12. In some embodiments, the window 20 may provide access to the skin 24 of the patient for application of a topical skin adhesive 27 at an insertion site of the catheter 12, the insertion site being disposed within the window 20. In some embodiments, a catheter tubing of the catheter 12 may extend beneath the anchor pad 14, as illustrated in FIG. 1A, for example, into a blood vessel of the patient. In some embodiments, the retainer 26 may include a clip, clasp, clamp, snap, button, strap, Velcro® or any other suitable mechanism for securing the portion of the catheter 12 to the anchor pad 14. In some embodiments, the retainer 26 may allow selective coupling of the portion of the catheter 12 to the anchor pad 14.

In some embodiments, the skin adhesive 27 may be disposed within the window 20 to secure the catheter 12 in place at the insertion site. In some embodiments, the window 20 may enclose the insertion site, which may facilitate controlled and contained application of the skin adhesive 27 at the insertion site. In further detail, the skin adhesive 27 may contact the skin 24 of the patient within the window 20 and/or a portion of the anchor pad 14 proximate the window 20, but may be prevented or discouraged from contacting skin 24 of the patient outside of the window 20, reducing a likelihood of a messy application of the skin adhesive 27. In some embodiments, the skin adhesive 27 may provide localized stabilization of the catheter 12 at the insertion site and/or may provide a seal around the catheter 12 at the insertion site, which may prevent infection. The skin adhesive 27 may also increase an indwell time for the catheter 12.

In some embodiments, the catheter 12 may be inserted into the patient prior to application of the skin adhesive 27 to the insertion site. Given the difficulty and usability challenges of holding the catheter 12 in position while applying the skin adhesive 27 to the insertion site, it may be advantageous to provide a means of securement of the catheter 12, such as the anchor pad 14 and the catheter securement mechanism, prior to application of the skin adhesive 27. Thus, in some embodiments, insertion of the catheter 12 and placement of the anchor pad 14 on the skin of the patient may occur prior to application of the skin adhesive 27. The anchor pad 14 and the catheter securement mechanism may facilitate greater control and accuracy in placement of the skin adhesive 27 at the insertion site, reduce an amount of skin adhesive 27 required, reduce a likelihood of a messy application of the skin adhesive 27, and reduce a risk of the catheter 12 becoming dislodged due to unintentional movement during application of the skin adhesive 27. Further, the anchor pad 14 and the catheter securement mechanism may eliminate a need for the clinician to hold the catheter 12 while the skin adhesive 27 dries, which may reduce a likelihood of the skin adhesive 27 bonding to a hand or glove of the clinician.

In some embodiments, an outer edge of the window 20 may be spaced apart from an outer edge of the anchor pad 14. In further detail, in some embodiments, the window 20 may be inset from the outer edge of the anchor pad 14. In some embodiments, the securement mechanism may be aligned with the window 20 such that the catheter 12 may extend outwardly from the securement mechanism to the window 20. In some embodiments, the catheter 12 may extend through a middle portion of the window 20.

In some embodiments, the skin adhesive 27 may include cyanoacrylate or another suitable glue or bonding material. In some embodiments, cyanoacrylate may include liquid monomers and may polymerize on contact with the skin, creating a flexible and/or semi-rigid layer. In these and other embodiments, liquid cyanoacrylate may be applied at the insertion site within the window 20 and may cure to a solid form within a period of seconds.

In some embodiments, the adhesive layer 22 may include any type or form of adhesive that is suitable for use with the methods and embodiments discussed in the present disclosure. In some embodiments, the adhesive layer 22 may be a spray-on adhesive, adhesive film, or any other type of adhesive application. In some embodiments the adhesive layer 22 may be formed of or include a polymer-based pressure sensitive adhesive. For example, when a polymer-based pressure sensitive adhesive is used in the adhesive layer 22, a bond may formed between the adhesive layer 22 and the skin 24 of the patient by applying light pressure between anchor pad 14 and the skin 24. In some embodiments, the adhesive layer 22 may include a slight liquid carrier that facilitates bonding with the skin 24. In some embodiments, the adhesive layer 22 may include a single-use glue, such that the adhesive layer 22 loses its adhesive properties once removed from the skin 24. In some embodiments, the adhesive layer 22 may include an antimicrobial agent to aid in maintaining sterility of the insertion site. In some embodiments, the adhesive layer 22 may include a multiple-use glue, which may allow the anchor pad 14 to be applied repeatedly.

In some embodiments, the window 20 may provide access to skin 24 of the patient for application of the skin adhesive 27 and/or a cleaning or disinfection agent at the insertion site of the catheter 12. In some embodiments, the cleaning agent may be disposed within the window 20 and may contact the skin 24 of the patient within the window 20. In some embodiments, the skin adhesive 27 and/or the cleaning agent may be prevented or discouraged from contacting the skin 24 of the patient outside of the window 20 and/or beyond an outer edge of the anchor pad 14. In some embodiments, the skin adhesive 27 and/or the cleaning agent may be wicked or pulled into the anchor pad 14 from the window 20 but may not contact the skin 24 beyond the outer edge of the anchor pad 14.

In some embodiments, a material of the anchor pad 14 may absorb a portion of the skin adhesive 27 and/or the cleaning agent and prevent spreading of the skin adhesive 27 and/or cleaning agent beyond the outer edge of the anchor pad 14. In some embodiments, the skin adhesive 27 and/or the cleaning agent may be contained within the window 20. In some embodiments, the anchor pad 14 may include any suitable medical grade material.
